I released a Mutant Future supplement called the Advanced Mutant Companion on DriveThruRPG. It's a collection of new rules, mutations, and races for Mutant Future. It expands the character creation and development options quite a bit.
*74 new mutations. These have been organized into random tables with the mutations from the Mutant Future core rules.
*5 new races and 2 revised races. Play as aliens and cyborgs.
*100 backgrounds. The background system is a flexible skill system which encourages role-playing and character development.
*18 feats. Fun abilities like pets, followers, and renown.
*New equipment rules. Give characters something to spend their money on.
If anyone would like a free copy to review on their gaming blog, send me a PM.
Also, I would love to hear any opinions. Especially any ideas on how to expand the Advanced Mutant Companion further.
